He was originally added to RuneScape as part of an April Fools' joke. Players had been requesting horses in the game for some time, and were excited to find out that Diango was to be added to sell "horses" in his store. However, Diango actually sells toy horseys, which are not rideable and are mostly useless. He has since been a part of several holiday events, such as the 2013 Hallowe'en event.
